How to connect Production server(Group/Server)?

Hi all,      

                I am having trouble  in a automation process that am doing. Since this was the first time in SAP scripting i was testing a automation in a test region Local configuration in SAP and the login script worked fine.But when i tried the same with the Production server(Messaging server) i am having trouble in login in. The code is as below

 sap = CreateObject("SAPGUI.Scriptingctrl.1")
 sapCon = sap.OpenConnectionByConnectionString(sapServer, False)
 With sapSession            .FindById("wnd[0]/usr/txtRSYST-BNAME").Text = sapID            .FindById("wnd[0]/usr/pwdRSYST-BCODE").Text = sapPassword            .FindById("wnd[0]/usr/txtRSYST-LANGU").Text = "EN"            '.FindById("wnd[0]").SendVKey(0)            '.FindById("wnd[0]/tbar[0]/okcd").text = "SE16"            '.FindById("wnd[0]").sendVKey(0)        End With

sapserver="xxxxx.xxxxx.xxx".

When i used it with the Prodution server i got the below error message Connection is refused

This was the first issue when i changed the the server in this format

sapserver="/M/xxxx.xxxxx.xxx/S//G/PG1"

i got this error msg

Logon Balancing parser error.
